Memorial Day is the official start-date for the second year of the Blue Star Museums program, where participating organizations offer free admission to active-duty military personnel and their families between Memorial day and Labor Day.

The Walker in Minneapolis participated in the inaugural year, and had 137 families take advantage of the program.
